Get a good, firm hold of the device. If you don't the power of the band will cause the device to flip round and get you.
Pull a band up over the rounded section above it.
Repeat this for all 4 bands.
Place the device on a sensitive area of a sub. Avoid the head, spine, lower back and stomach area.
NB... I need a better image for this, if any pretty subs wish to model the use of this I would be very grateful.
Turning the handle releases each band in turn.
Again a better image here is needed. Any pretty sub willing to help?
